As part of thier company heritage all G&G gearboxes are made with one of the highest precision and quality an airsoft company has to offer. Here G&G presents its GR4 CQB-S offering of the famous M4/16 family style guns with a suppressor compact barrel to engage targets in close quarters combat situations. Coming to you in a special tan and black two tone finish to provide a stylish and versatile camouflage scheme. It sports a modern configuration with railed hand guards, collapsible crane stock, a reinforced trigger guard, and an exclusive tactical grip 120-round mid-capacity magazine. There is Rail Accessory System (RAS) along the top length of the receiver mounting red dot sights, scopes, backup iron sights, and other accessories. The quad rail in the front features 4 soft rubber ladder rail panels to help protect the rails from wear and provides a comfortable place for the shooter to grip onto. If you opt to remove them you can replace them with additional attachments such as vertical grips, lights, and lasers. Sling points are ambidextrous and can be found at the rear of the gun.

Along side its Pneumatic Blow-Back system, it is a very reliable and balanced gun, shooting in the 350 FPS range - the maximum allowed FPS for many close quartered combat scenarios in many airsoft arenas. All this is housed within its high impact nylon fiber polymer body which sheds off weight and cost to give starting users a head start or veteran players an excellent platform for custom builds. While the revolutionary and patented blow-back system uses leftover compression of each shot to power a gun's bolt to pull back and forth simulating the cycling action of real steel guns providing a realistic, and satisfying, touch to your guns. Traditionally this feature was expensive and if not done correctly: detrimental. Mainly because it encompasses jury-rigging the bolt assembly to the internal gearbox's which was difficult to install and remove, while putting strain on the gun's crucial parts.

Note this gun does not come with a battery and charger, however investing in a stronger 8.4V or 9.6V battery and a smart charger is always a recommendation - oppose to using lesser batteries and chargers that other airsoft guns often come with. This gun was designed for the player who wants to take a serious step into airsoft without the unnecessary high cost of admission.
